RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 759,175, dated May `3,1904.

Application filed February 13, 1904. Serial No, 198,437. (No model.)

To all wiz/0m, it may coli/carve.-

Be it known that I, SYLVANUS HARTEN- STEIN, a citizen of the UnitedStates, residing' at Easton, in the county of Northampton and State ofPennsylvania, have invented new and useful Improvements inRailroad-Ties, of which the following is a specification.

My invention relates to new and useful improvements in railroad-ties;and its object is to provide a spring-tie of simple construction whichwill form a cushion for the rails connected thereto and will permit theproduction of a smooth track which will prevent the violent jars whichare ordinarily incident to the movement of a railroad-car.

With the above and other objects in view the invention consists of a tiecomprising similar plates slidably mounted upon guide-pins and havingsprings interposed between them and arranged on the pins. Suitablerail-engaging devices are secured to the upper plates of the tics.

The invention also consists in the further novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, and in which# Figure l is a plan View of rails connectedto ties constructed in accordance with my invention; and Fig. 2 is alongitudinal section through one of the ties, the central portion of thetie being removed.

Referring to the figures by numerals of reference, l is a base-platehaving, preferably, two parallel series of pins 2 extending therefrom,and. these pins project through apertures 3, formed-within a top plate4. Heads 5 are formed at the ends of the pins, so as to preventdisplacement thereof, and springs 6 are coiled about the pins and abutat their ends upon the inner faces of the two plates l and 4.Rail-engaging blocks 7 are adapted to be secured upon the upper plate 4by means of bolts 8 or in any other suitable manner and when overlappingthe base-anges of rails 9 will securely hold them upon the plate 4.

It will be seen that a tie constructed 'in the manner herein describedis very simple and resilient, and at the same time the rails connectedthereto are held in proper relation to each other. Any downward pressureupon the plate 4 will cause said plate to slide downward on the pins 2and compress the springs 6, and these springs will promptly return theupper plate 4 to its norm al position when pressure is removedtherefrom.

In the foregoing description l have shown the preferred form of myinvention; but l do not limit myself thereto, as l am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and l therefore reserve theright to make such changes as fairly fall within the scope of myinvention.

Having thus described the invention, what is claimed as new isl. In arailroad-tie, the combination with a base-plate having pins extendingtherefrom; of atop plate slidably mounted upon the pins, springs coiledabout the pins and interposed between and bearing upon the plates, andmeans upon the top plate for securing rails thereto.

2. The combination with a base-plate having parallel series of pinsextending therefrom, of an apertured top plate slidabl y mounted uponthe pins, springs coiled about the pins and interposed between andbearing against the plates, heads upon the pins, and means upon the topplate for securing rails thereto.

3. The combination with a base-plate having parallel series of pinsextending at right angles, and heads at the ends of the pins; of anapertured top plate slidably mounted upon the pins, springs inclosingthe pins and bearing at opposite ends upon the inner faces of the baseand top plates, and rail-engaging blocks detachably secured to the topplate.

ln testimony whereof I aiiix my signature in presence of two witnesses.

SYLVANUS HARTENSTEIN.
